Abstract

764,647. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 10, 1955 [Feb. 17, 1954], No. 3981/55. Class 38(5) In an air-blast switch having contacts 4, 5 arranged within a compressed air container 1, the opening of an outlet valve 17, 18 allows the compressed air in the container to move the contact 5 to the open position in which a valve member 6 carried by the contact blocks the outlet for the compressed air so that the airblast occurs only during the period of contact opening. The outlet 17 is opened by the valve element 18 when pressure is applied to a membrane 19, the element 18 in its opened position closing the outlet of a pipe 22. The air blast occurs through the tubular contact 5, openings 13 and the outlet 17 when the contact 5 is moved by the air pressure acting on it, its movement being braked by a piston 8 moving in a cylinder 9 connected through a throttle valve 10 to the container. When the member 6 abuts a seating 14, the blast ceases. To reclose the switch, the membrane 19 is relieved from pressure and a spring 23 moves the valve element 18 to the right to close the outlet 17 and open the pipe 22. This equalizes the pressure above and below the member 6 and a spring 12 recloses the contacts.
